void mfem::TMOPComboIntegrator::AddMultGradPA ( const Vector x,
Vector y 
) const
virtual

Method for partially assembled gradient action.

All arguments are E-vectors. This method can be called only after the method AssembleGradPA() has been called.

Parameters
[in]xThe gradient Operator is applied to the Vector x.
[in,out]yThe result Vector: \( y += G x \).

Reimplemented from mfem::NonlinearFormIntegrator.

Definition at line 3236 of file tmop.cpp.

void mfem::TMOPComboIntegrator::AddMultPA ( const Vector x,
Vector y 
) const
virtual

Method for partially assembled action.

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.

Reimplemented from mfem::NonlinearFormIntegrator.

Definition at line 3228 of file tmop.cpp.

void mfem::TMOPComboIntegrator::AddTMOPIntegrator ( TMOP_Integrator ti)
inline

Adds a new TMOP_Integrator to the combination.

Definition at line 1541 of file tmop.hpp.

void mfem::TMOPComboIntegrator::AssembleElementGrad ( const FiniteElement el,
ElementTransformation Tr,
const Vector elfun,
DenseMatrix elmat 
)
virtual

Assemble the local gradient matrix.

Reimplemented from mfem::NonlinearFormIntegrator.

Definition at line 3155 of file tmop.cpp.

void mfem::TMOPComboIntegrator::AssembleElementVector ( const FiniteElement el,
ElementTransformation Tr,
const Vector elfun,
Vector elvect 
)
virtual

Perform the local action of the NonlinearFormIntegrator.

Reimplemented from mfem::NonlinearFormIntegrator.

Definition at line 3139 of file tmop.cpp.

void mfem::TMOPComboIntegrator::AssembleGradDiagonalPA ( Vector diag) const
virtual

Method for computing the diagonal of the gradient with partial assembly.

The result Vector diag is an E-Vector. This method can be called only after the method AssembleGradPA() has been called.

Parameters
[in,out]diagThe result Vector: \( diag += diag(G) \).

Reimplemented from mfem::NonlinearFormIntegrator.

Definition at line 3220 of file tmop.cpp.

void mfem::TMOPComboIntegrator::AssembleGradPA ( const Vector x,
const FiniteElementSpace fes 
)
virtual

Prepare the integrator for partial assembly (PA) gradient evaluations on the given FE space fes at the state x.

The result of the partial assembly is stored internally so that it can be used later in the methods AddMultGradPA() and AssembleGradDiagonalPA(). The state Vector x is an E-vector.

Reimplemented from mfem::NonlinearFormIntegrator.

Definition at line 3211 of file tmop.cpp.

void mfem::TMOPComboIntegrator::AssemblePA ( const FiniteElementSpace fes)
